estimating fetal weight in utero, for better management of pregnancy and appropriate timing of delivery especially in high-risk pregnancies is necessary. our purpose to evaluate a simple method in estimating fetal weight in iranian pregnant patients and also to compare was with a previous western study. this study was carried out in arash hospital, tehran university of medical sciences in 1996-...

This investigation evaluated the impact of collecting data on early fetal deaths (less than 20 weeks' gestation) on a birth defects surveillance system. Data were obtained from the Hawaii Birth Defects Program (HBDP), a statewide registry for Hawaii with active case ascertainment methodology. In 1986 through 1997, 257 early fetal deaths with birth defects were identified, representing 2.2% of t...

Background Congenital heart disease (CHD) is the most common lethal congenital anomaly. Early diagnosis of CHD by fetal echocardiography based on maternal and fetal indications is important and lifesaving. The aim of study was to assess the referral aspects of pregnant women to pediatric cardiologist. Materials and Methods This was a retrospective cross-sectional study on 250 documents of refer...

Fetal heart abnormalities are the most common congenital anomalies and are also the leading cause of infant mortality related to birth defects. More than one-third of all malformations found after delivery are congenital heart defects. The prenatal detection of fetal cardiac structure is difficult because of its small size and rapid movements but is important for the early and effective diagnos...

OBJECTIVE To define the prevalence of major cardiac defects according to nuchal translucency (NT) thickness at the 11 to 13 + 6-week scan in fetuses with normal karyotype. METHODS Specialist fetal echocardiography was carried in 6921 fetuses with normal or presumed normal karyotype at a median gestation of 20 (range 12-35) weeks. The indications for fetal echocardiography were increased NT th...

OBJECTIVE To determine whether assessment of ductus venosus flow at 11-13 weeks' gestation improves the detection rate of cardiac defects achieved by screening with nuchal translucency (NT) thickness. METHODS Prospective first-trimester screening for aneuploidies, including measurement of fetal NT and assessment of ductus venosus flow. The performance of different combinations of increased fe...

Developmental defects of enamel (DDE) are important markers stress as they arise from the disruption ameloblastic activity during matrix secretion and mineralization. Defects on crowns deciduous dentition provide insights into maternal–fetal health because can emerge intrauterine development a result gestational issues. The presence previous defective represents one most predisposing causes car...

A variety of developmental defects occur as a result of prenatal exposure to alcohol (ethanol) in utero. In humans [5], those defects are collectively classified as Fetal Alcohol Spectrum Disorders, with Fetal Alcohol Syndrome [6] (FAS) representing the more severe defects. FAS is defined by preand post-natal growth retardation [7], minor facial abnormalities, and deficiencies in the central ne...
